IN CIRCUIT ESR-METER

Why measure ESR? A capacitors physical construction dictates that most capacitor failure modes will adversely affect a capacitors ESR. When a capacitor fails ESR goes up to as high as infinity, depending upon the particular failure mode. An open cap measures infinity. Slight dielectric changes cause ESR to go up by several ohms. Standard capacitor meters cannot detect any change in ESR therefore they miss bad capacitors leading to time consuming "Tough Dog" repairs. A good percentage of your capacitor troubles are caused by an increase in ESR! The Capacitor Wizard won't be fooled!!

The Capacitor Wizards method of measurement is based on sound BASIC ELECTRONICS. It is an AC Ohm Meter with its Frequency, Waveform and Measurement Point carefully chosen to maximize its ability to measure low values of ESR (Equivalent Series Resistance) on capacitors of 1uf and up. If a capacitor opens up the Capacitor Wizard measures infinity indicating a drastically bad capacitor. If a capacitor changes value slightly the ESR goes up indicating a bad capacitor. In switching and high current applications (TV Horiz / Vert, Switching Power Supplies, Motor Start and Run Caps) the difference between 0.2 ohms ESR and 2 ohms ESR is very significant!

Many occupations can benefit from using the Capacitor Wizard: TV Repair, Printer Repair, Switching Power Supply Repair, Computer Monitor Repair, Air Conditioning and Refrigeration, Medical Electronics, Electric Motor Repair to name a few.
